aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...

To determine if donepezil, an acetylcholinesterase (AChE) inhibitor, improved the assimilation of cognitive training by older adults with memory complaints, we gave 168 nondemented, community-dwelling volunteers with memory complaints either 5 mg of donepezil (Aricept) or placebo daily for 6 weeks in a randomized, double-blind, placebo-controlled trial. The dosage rose to 10 mg daily for anothe...

Background : Cholinesterase inhibitors (ChEIs) which have been widely used clinically are known to have diverse actions on the neuromuscular synaptic transmissions, suggesting that inhibiting cholinesterase (ChE) might not be their only mode of action. ChEIs interact with the nicotinic acetylcholine receptor (nAChR) macromolecule as a weak agonist, and as a modulator inducing desensitization an...

Acetylcholinesterase inhibitors are commonly used to treat patients with dementia with Lewy bodies. Hippocampal atrophy on magnetic resonance imaging and amyloid-β load on positron emission tomography are associated with the Alzheimer's disease-related pathology in patients with dementia with Lewy bodies. To date, few studies have investigated imaging markers that predict treatment response in ...

DMNG-3(3β-Methyl-[2-(4-nitrophenoxy)ethyl]-amino]con-5-enine), is a new and the potentially most potent acetylcholinesterase inhibitor recently obtained from conessine by N-demethylation and nucleophilic substitution reaction. In the present study, a step-down passive avoidance test was used to investigate whether DMNG-3 could modulate impairment of learning and memory induced by scopolamine, a...

objective(s): alzheimer's disease (ad) is a neurodegenerative disorder in elderly patients. decrease in cholinergic neurotransmission is the main known cause in the pathophysiology of the disease. improvement and potentiation of the cholinergic system could be beneficial for treatment of the ad. acetylcholinesterase inhibitors such as donepezil can enhance the duration of action of acetylc...

Arachidonylsulfonyl fluoride (3), reported here for the first time, is similar in potency to its known methyl arachidonylfluorophosphonate (2) analogue as an inhibitor of mouse brain fatty acid amide hydrolase activity (IC(50) 0.1 nM) and cannabinoid CB1 agonist [3H]CP 55,940 binding (IC(50) 304-530 nM). Interestingly, 3 is much more selective than 2 as an inhibitor for fatty acid amide hydrola...

We are confronted with a large and steadily growing number of bioactive compounds, including drugs, pesticides, and industrial by-products. The assessment of target specificity and potential toxic effect on human health and the environment generates a strong demand for robust and cost-effective models with high predictive power. We investigated the potential of the zebrafish embryo as a whole o...
